CNC Machined Multi-Hole Precision Fixture Base Plate

As a core load-bearing component for automated testing or assembly lines, this plate-like structure features a large central rectangular cutout and a dense layout of peripheral holes. This design allows for clearance of internal components and rapid positioning of external modules. Laser-etched serial numbers on the side indicate traceability management capabilities. It is commonly used in tooling and fixture systems within the electronics, semiconductor, and precision machinery industries to ensure stable reference positioning during high-frequency assembly operations.

The part surface exhibits a uniform brushed metal texture. Countersunk holes, through-holes, and threaded holes of various specifications are distributed around the corners and edges for securing dowel pins or connecting actuators such as cylinders. The machining focus lies in controlling positional tolerances between hole patterns, especially the positioning hole group around the central window, which requires extremely high coaxiality to accommodate precision pins or sensors. Additionally, flatness around the large opening must be strictly controlled to prevent warping caused by stress release after material removal, ensuring optimal assembly fit.

Leveraging our factory's high-precision vertical machining centers and Hexagon CMMs, we effectively handle the manufacturing of such parts with multiple features and high positional accuracy requirements. For base materials such as aluminum, stainless steel, or mold steel, we provide one-stop solutions ranging from rough and finish machining to deburring, anodizing, or nickel plating. Please provide 2D/3D drawings with complete tolerance annotations to evaluate specific machining processes and obtain an accurate quote.
